DUST-GUARD For: AUTOCARS.

SPECIFICATION forming part of Letters Patent No. 775,595, dated November22, 1904'.v

Application filed March 31 1904. serial No. 201,003. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. BROWN, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Dust-Guards forAutocars, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings.

This invention relates to dust-guards for autocar-s, and moreparticularly to the type of guard wherein a conduit is formed around therear portion of the side and the back of the car, an example of suchtype being shown in my prior patent, No. 7 42.580, granted October 27,1903.

The object of this invention is to provide a guard of the type shown insaid patent, which guard shall effectively collect the clean air anddischarge thesame at the rear of the vehicle to prevent the dust-ladenair at the rear of the vehicle from being thrown over the top edge ofthe same, which will not materially alter nor detract from theappearance of the vehicle nor interfere with the convenience or comfortof the passengers.

Referring to the drawings, Figure 1 represents a view in perspective ofone side of the rear end of an autocar having my invention appliedthereto. Fig. 2 represents a rear elevation of such autocar, the partsbeing broken away to show the internal construction of the conduit. Fig.3 represents a horizontal sectional view of the rear portion of suchautocar, said section being taken through the airconduits, themud-guards being shown in elevation. Fig. 4 represents averticalsectional detail showing said conduit.

Describing the parts by letters, A represents the body of the autocar,said body being of the familiar tonneau form having the overhanging rearseats O.

B represents the mud-guards, which flare outwardly over the wheels. Therear portions of the sides a and the backa' of said body are preferablydrawn in or contracted somewhat as compared with the ordinary autocar,so as to be overhung by the seats O, as shown particularly in Figs. 2.3, and 4. The skirt c,,which forms the outer wall of the airconduit,.ismade by extending the back of the seat 0, at the rear of the side and atthe rear of the end of the car, downwardly to about the level .of thefloor (0 The upper front portionof such skirt is flared outwardly, asshown at 0 to merge with the outwardly and upwardly flaring mud-guard B.The lower front portion of said extension is at about the level of thefloor a. A bottom closure D in about the plane of the floor (0 extendsfrom the lower portion of the side and back of the car to the skirt.There is thus formed below each seat C a conduit E,

open at its front and rear ends only and of which the body forms theinner wall and the seat the top wall. This conduit has a funnelshapedopening a at its front end formed by the upwardly and outwardly flaringmudguard B, the bottom D, the side a, and the flaring portion 0 of theskirt or seat-back ex tension 0'. The air is taken from a sufficientdistance above the ground to prevent the same from being laden withdust, while the flaring-mouth of the conduit insures the collection of asuificient amount of relatively pure air to break up the partial vacuumat the back of the vehicle, and thus prevent the dust-laden air at therear of the vehicle from flowing over the rear top edge of the same.

In order to insure that the air discharged from the relatively lowconduits E E shall be effective to protect the rear top edge of the carfrom the dust-laden air behind the vehicle, I impart to such airdischarged from the conduits an upward inclination by giving an upwardflare to the bottom D at the discharge end of the conduit, as shown atcl.

By the construction above set forth I have produced a dust-guard whichis neat in appearance, which will effectively collect the relativelypure air employed to prevent the formation of a vacuum at the rear ofthe carriage, which will not materially alter nor detract from theappearance of the vehicle to which it is attached, and which will notinterfere with the comfort and convenience of the occupants of thevehicle. 1

I claim 1. The combination with an autocar, of a skirt'extending fromthe lower portion of the car-body as high as the seat, said skirt beingspaced from the body and extending along the rear portion of the side ofthe body around the rear end thereof, substantially as described.

2. The combination with an autocar, of a pair of curved skirts, one oneach side of said car, each of said skirts extending from the lowerportion of the body as high as the seat, said skirts being spaced fromthe body andextending along the rear portion of the sides and around therear end thereof, substantially as described.

3. The combination with an autocar, of a flaring mud-guard partiallysurrounding one of the rear wheels of said car, of a skirt extendingaround and spaced from the lower portion of the side and end of saidcar, the forward end of said skirt being secured to said mud-guard,substantially as described.

4. The combination with an autocar, of flaring mud-guards for the rearwheels, each of said guards extending partly around its respectivewheel, of a skirt extending around and. spaced from the lower portion ofeach side and its adjacent end portion, the forward end of said skirtbeing flared outwardly and secured to its corresponding mud-guard,substantially as described.

5. The combination with the side and end of an autocar, of a seat in therear portion of said car, a back for said seat, said back extendingalong the rear portion of the side and around a portion of the end ofthe car and overhanging the body portion therebelow, a skirtconstituting an extension for the back of said seat and extending nearthe bottom of the body and spaced from said body to form an-air-conduit,substantially as described.

6. The combination with the side and end of an autocar, of a seat in therear portion thereof, a portion of said seat projecting beyond the sideand end, a back for said seat, a skirt, forming an extension for theseat-back, extending along the side and around the end of the car andspaced from the side and end to form an air-conduit, and a bottom forsaid conduit, substantially as described.

7. The combination with the side and end of an autocar, of a seat in therear portion thereof overhanging said side and end, of a rear wheel, anoutwardly-flaring mud -guard extending partly around said wheel, a backfor said seat, a skirt forming an extension for said back and extendingfrom the seat downwardly in proximity to the bottom of the carbody, saidskirt also extending around a portion of the end of the car and flaringoutwardly at its forward end to engage said dust-guard, substantially asdescribed.

8. The combination with an autocar, of a curved skirt extending alongthe side and around the end of the car-body to form an openendedconduit, and a closure for the bottom of said conduit, said closureflaring upwardly at the rear or discharge end of the conduit whereby theescaping air is directed upwardly, substantially as described. 7

9: The combination with the sides and end of an autocar, of a pair ofupwardly and outwardly flaring mud-guards partially surrounding the rearwheels, of a sheet secured to each side of the body and extending alongthe rear portion of the side of the car and around the rear end thereof,said skirt being spaced from said side and end to form an air-conduitand having its upper edge flaring outwardly and secured to saidmud-guard, and a closure for the bottom of said conduit, the forward endof said closure flaring outwardly and being secured to the mud-guard,substantially as described.

10. The combination with an autocar, of two curved skirts, eachextending along a side of the car and a short distance around the rearend thereof to form an air-conduit, a bottom closure for each of saidconduits, the portion of said closure adjacent to the rear or dischargeend of each conduit flaring upwardly, substantially as described.

11. The combination with an autocar, of a curved skirt extending alongthe side and around the end of the car-body to form an openendedconduit, said skirt extending from near the bottom of said body to theheight of the rear seats thereof, a bottom closure for said conduit, theportion of said closure adjacent to the rear or discharge end of theconduit flaring upwardly, substantially as described.

12. The combination with the side and end of an autocar, of aseat in therear portion of said car, said seat overhanging the rear portion of saidside and a portion of said end, of a curved skirt extending from thelevel of said seat downward and forming an air-conduit around the rearportion of the side and the adjacent end portion of the car, and aclosure for the bottom of said conduit, the portion of said closureadjacent to the rear or discharge end of said conduit flaring upwardly,substantially as described.
